GB/T 32366-2025 "Biological degradation polybutylene terephthalate-adipate (PBAT) " standard system defines the classification of PBAT products, and puts forward clear requirements for physical properties such as appearance, density, melt mass flow rate, tensile strength, fracture elongation, etc. Mechanical Properties, as well as biological degradation rate, heavy metals content and other environmental indicators. At the same time, the test methods and inspection rules of each performance are specified in detail, and the product labeling, Encasement, transportation and storage specifications are clarified, which provides guidelines for the whole life cycle mass control of PBAT materials and the standardized development of the industry.
